Sony plans largest ad campaign in 'many years' to launch new Xperia smartphones

Sony didn't just reveal some newsmartphones at its Mobile World Congress press event today. It also took the opportunity to announce that it will be launching what Sony Mobile CMO Steve Walker describes as "by far the largest brand advertising campaign that we have run for many years." He went on to say that Sony would be "significantly increasing" its marketing investment in 2012, but failed to get any more specific than that, noting only that the company would be "engaging consumers in new and very creative ways." There's also no word on when that campaign might start, but the company's two latest smartphones are slated to roll out sometime in the second quarter of this year.
